Rupert Grint

Grint was the first of the 'Harry Potter' principals to branch out into non-wizard roles, co-starring in 2002's 'Thunderpants' when he was 14. Like Daniel Radcliffe and Emma Watson, he saw his salary rise exponentially over the course of the 'Potter' series, to the point where he is now said to be worth $50 million at age 23. One famous indulgence his wealth has made possible: his own ice cream truck.
